PLAN CHECK COMMENTS
Sheet A3.35 – Specify truncated dorm detail where pedestrian route crosses vehicular traffic ways.
Sheet A7.1.2 – Door “212”, Sheet A7.1.3- Door “312”, Sheet A7.1.4- Door “412”, Sheet A7.1.5 – Door “512”:
The assumed property line is located along grid-line “R”. The Fire Separation distance is between 0 to less than 3 feet. Per CBC Table 705.8, openings are not permitted. Verify openings on door “212”, “312”, “412”, and “512”.
Sheet A1.5 – Floor plan shows garage stairway located near room “449” terminates on the fourth floor. It appears the stairway was designed as a second exit on the 6th floor of the garage due to the number of occupant load increased from the swimming pool area. Once the occupants reached the vertical exit enclosure, the level of fire protection shall maintain throughout until occupants reaches the exit discharge. On the fourth floor, the vertical enclosure terminates at the one-hour corridor of the building. In order to maintain the same level of fire protection as the vertical stairway enclosure, the corridor shall be designed as an exit passageway per CBC Section 1023. The issue with this design is the openings at storage doors at the corridor. Openings at the exit passageways are limited to the exit-access space necessary for exit and exterior exit.
Sheet A2.2-Fourth Floor – 10 Fire walls are utilized in this building in order to lower the Type of Constructions required for the entire building. The fire areas were reduced to the maximum allowable area per story and per building on a Type III-A construction. Per CBC Section 706.1, each portion of a building separated by one or more fire walls that comply with the provisions of this section shall be considered a separate building. When fire walls are considered as separate buildings, other Code provisions shall follow these criteria such as allowable area design in chapter 5 and Type of construction design in chapter 6. On egress system design, each building shall have its own egress system consist of exit access portion, exit portion, and exit discharge portion in accordance with CBC chapter 10. There are “buildings” on this structure do not have its own vertical exit enclosure. Exit system is designed using travel distance to another “building”. For example, the “building” on the East side of the garage require occupants on the fourth floor travel pass through Fire wall to reach exit stairway “ST-4” and the second required exit is located on two adjacent “building” for exit stairway “ST-3”. Please provide justification for using Fire Walls as a separate “building” for certain Code provisions, but a single “building” is assumed in means of egress system.
Sheet G2.1
Under the “Frontage-Calculations” Tables, revise the numbers on “Aa”. “Aa” is the allowable floor area per story. The number shows on the table is the allowable floor area for the building.
Under the “Frontage-Calculations” Tables, Provide tabulation for “Total allowable area” per building.
Under the “Frontage-Calculations – Area 1” Table, building perimeter “F” appears to be miscalculated. Open space of East side of the building is only 10 feet, and open space on North side of the building is only 14’. The minimum qualified open space is 20 foot. The “Area increase frontage factor, (If)” should be substantially lower than the calculated value (If) = 62.47%. This calculation affects the maximum allowable area for the story and the building. Please verify calculations for each “building” to ensure the actual floor-area does not exceed the maximum allowable area per each building.
SHEET A6.1- Legend references 3 hour firewall on sheet AD1.8 and AD1.9. However, sheet AD1.8 and AD1.9 is missing.
This building is of Type III-A construction, provide /show:
Continuous drywall behind all tubs is required unless the walls are within the unit and non- bearing. Back to back tubs with a common plumbing wall are impractical in 1-hour buildings.
All interior bearing walls shall be constructed of notless than 1-hour fire-resistive construction. (T-601)
Attic access openings in 1-hour ceiling can be 2layers of 3/4" plywood or one layer of 1-5/8" T&Gmaterial, self-closing.
All openings in floors are required to be enclosed bya shaft having wall, floor, and ceiling of ______2____hour fire resistive construction. (713.1)
Recessed ceiling light fixtures must be boxed aroundwith 5/8" Type “X” drywall” to maintain the 1-hourceiling assembly.
Continuous drywall is required behind all electricalservice panels, fire hoses and medicine cabinets.
Exhaust fans from the bathroom must enter throughthe wall. Dampers are required if the ceiling ispenetrated (717.5)
Plumbing penetration through horizontal occupancyseparations shall be boxed out and filled with
approved safing material. Insulation is not approved.
Penetration of the 1 hour ceiling by ducts from the FAU and the stove hood require dampers (use a ductless hood whenever possible). Attic units (including heat pumps) require dampers at all ceiling penetrations. (711)
Steel beams and columns shall be protected asrequired for 1-hour protection. Where ceiling formsthe protective membrane for fire-resistiveassemblies (occupancy separations and rated
roof/ceiling or floor/ceiling assemblies), theconstruction (floor joists) and their supportinghorizontal structural members (beams) need not beindividually fire protected except where such
members support directly applied loads from morethan one floor or roof. The required fire resistanceshall not be less than that required for individualprotection of members. (704.3)
All plumbing penetrations thru walls which requireprotected openings (Fire walls, Fire barriers, Firepartitions) are required to be galvanized or cast ironpiping.
FIRE PROTECTIONPlans shall indicate how required structural and fire resistive integrity will be maintained where a penetration will be made for electrical, mechanical, plumbing and communication conduits, pipes and similar systems. CBC Section 106.1.1 and CBC Chapter 7. Note on the plans the ICC Research Report number, U.L. number, State Fire Marshal number, or approval number of another agency accepted by the City of Santa Ana.
